## The solubility rules outlined in Chapter 6 say that Ba(OH)2, Sr(OH)2, and Ca(OH)2 are marginally soluble hydroxides. Calculate the pH of a saturated solution of each of these marginally soluble hydroxides.

(I)

Interpretation Introduction

Interpretation: The pH of a saturated solution of the given hydroxides is to be calculated.

Concept introduction: The pH of a solution is defined as a figure that expresses the acidity of the alkalinity of a given solution.

The pH of a solution is calculated by the formula, pH=log[H+]

The sum, pH+pOH=14

### Explanation of Solution

Explanation

To determine: The pH of a saturated solution of the given hydroxides.

The [OH] is 0.22mol/L_ .

The Ksp of Ba(OH)2 is 5.0×103 .

The dissociation reaction of Ba(OH)2 is,

Ba(OH)2Ba2++2OH

The solubility of Ba2+ is assumed to be smol/L .

The solubility product of dissociation of Ba(OH)2 is calculated by the formula,

Ksp=[Ba2+][OH]2

The solubility of Ba(OH)2 can be calculated from the concentration of its ions at equilibrium.

It is assumed that smol/L of solid is dissolved to reach the equilibrium. The meaning of 1:2 stoichiometry of salt is,

smol/LBa(OH)2smol/LBa2++2smol/LOH

Formula

The solubility product of Ba(OH)2 is calculated as,

Ksp=[Ba2+][OH]2=(s)(2s)2=4s3

Where,

• Ksp is solubility product
